Brewfather and AG kits

[AnimatedGIF]

I'm soon to brew an AG kit from the Malt Miller. I am fairly new to AG brewing and have been using Brew Father with great success (I mostly like it for the strike water calculations, for example). Is there a way I can do these calculations without knowing the exact recipe?
EDIT: I just found the strike water calculator on the app.

Similarly, I like the water additions calculations. I can't seem to find how to calculate these without doing a recipe.

The kits should include a breakdown of the malt bill for you to enter. Which kit is it?

It's Red Triangle Draught Bass Tribute. You're right, it is. Sorry. I had misplaced the sheet and just found it, complete with all ingredients required. Perfect. Thanks.
